Originally published in the 1940s, Paul Hindemith's remarkable textbooks are still the outstanding works of their kind. In contrast to many musical textbooks written by academic musicians, these were produced by a man who could play every instrument in the orchestra, could compose a satisfying piece for almost every kind of ensemble, and who was one of the most stimulating teachers of his day. It is therefore not surprising that many years later these books should remain essential reading for the student and the professional musician.
